Question

xi) A ball of mass 100 g dropped on the
ground from 5 m bounces repeatedly.
During every bounce 64% of the
potential energy is converted into kinetic
energy. Calculate the following:
(a) Coefficient of restitution.
(b) Speed with which the ball comes up
from the ground after third bounce.
(c) Impulse given by the ball to the
ground during this bounce.
(d) Average force exerted by the ground if this impact lasts for 250 ms
(e) Average pressure exerted by the ball on the ground during this impact if contact area of the ball is 0.5cm2
​
